since it is quite obvious you like the raising the dead and having zombies running around middle earth. I feel its tasteless and NOT what Tolkien meant. Raising spirits is one thing but reanimating the dead is something altogether different. which I still feel is not what Tolkien meant.

In Morgoth’s Ring – The Later Quenta Silmarillion (11) Of Re-Birth and Other Dooms of Those that Go To Mandos CT – acting as his father’s editor – finally let’s us in on the secret that has been teasing us since The Hobbit was first published.Morgoth’s Ring was published in 1993 – The Hobbit in 1937 (revised edition 1966). So, 56 years on the ‘Necromancer’ and his secrets were finally revealed. Yet, given the restricted circulation of HOME 10 it is highly probable that millions of Tolkien fans do not yet know quite what Tolkien meant by ‘the Necromancer’ other than its more general sorcerous application.In Morgoth’s Ring the story finally unfolds!1. To understand the unfolding we have firstly to become familiar with two terms: fea (pl. fear) and hroa (pl.hroar) or hron / hrondo (pl. hroni)2. fea (pl. fear) soul, indwelling spirit , of an incarnate being3. hroa (pl.hroar) or hron / hrondo (pl. hroni) body (of an incarnate being)4. We also need to understand that the fea (spirit) is unable to be coerced or forced. Thus it cannot be made to go to Mandos even if it has been properly summoned. The summons may be refused.5. Those fear (spirits) that refuse the summons and remain in ME wander homeless in the world- they have no personal hroa (body) or hroar (bodies) to inhabit. Many haunt trees, or springs, or hidden places that they once knew.6. Not all of those who refuse the summons are kindly – many are stained by the Shadow. Indeed, the refusal of the summons is in itself a sign of taint.7. The Valar who rule Arda have thus forbidden the living to commune with the Unbodied, though the latter may desire it, particularly the more evil sort.8. Some of the Unbodied are filled with envy, bitterness, and grievance and some of these were enslaved by Sauron, and even though he is gone, they still do his work.9. They do not speak truth or wisdom and for the living to call on them is perilous.10. Attempting to master them and binding them to one’s will is wicked . They are the practices of Morgoth, and the necromancers who do this are followers of Sauron.11. The evil Unbodied will possess the hroa (body) of a living person if possible. So communing with them is doubly perilous as it could involve the loss of one’s hroa (body)12. The evil Unbodied, if given friendship by the living may seek to eject the fea (spirit) of the living person and occupy their hroa (body). The resultant battle can either cause grave injury to the living person’s body, or result in its actual possession by the Unbodied, and the dispossession of the living person’s fea or spirit.13. The Unbodied may try and plead for shelter, and if allowed to enter the hroa (body) of a living person will seek to enslave and use both the fea ( spirit) and hroa (body) of the living person for its own purposes, ultimately probably expelling the original fea (spirit) 14. Sauron is said to have done these things, and to have taught his followers how to achieve them- hence his name ‘Necromancer’.

in the Lay of Leithian in the passage which describes Beren’s and Finrod’s approach to Tol Sirion, and description of Sauron’s(Thu’s) occupation of it. There, besides commanding a host of spirits, he is also attributed the power of injecting spirits into the bodies of monsters(wolves)

More useless internet nonsense taken from someone who did research from Tolkien's writings, but still I see no mention of actually raising and reanimating dead corpses.. I merely see possession of the living be they human or animal by a dead spirit...
